Just a thought...you said you started adding wellwater. Have you used this well water much or any before? Have you ever had that well water tested? I don't use my well water even though I thought it was GREAT I had a well but...the chemistry was horrible! I used it to water a garden one year...killed everything. Used it to water peach trees and fig trees...killed everything!! No way I'm chancing it in my pond! Just make sure you have good pond water. Good luck.

Dear Alcohol, We had a deal where you would make me funnier, smarter, and a better dancer... I saw the video... We need to talk.
